DETAILED DESCRIPTION

[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] See also Figures 1 to 5 In an embodiment of the present invention, a cerebral vascular puncture and fixation device for neurointervention includes a puncture needle body 1, a catheter is provided on the puncture needle body 1, a heparin cap body 11 is connected to the catheter, a first transparent dressing body 2 for attaching a puncture position is provided on the outside of the puncture needle body 1, a central setting hole 21 is opened in the first transparent dressing body 2, the puncture needle body 1 corresponds to the central setting hole 21, a catheter attachment and fixing component 4 for limiting the position of the catheter is provided on the outside of the puncture needle body 1, the catheter attachment and fixing component 4 includes a first high platform 42 and three adhesive tape bodies 41, the three adhesive tape bodies 41 are respectively staggered on the outside of the catheter, the first high platform 42 supports the catheter to be lifted, the heparin cap body 11 is positioned with the central setting hole 21 as the center, a second high platform 5 for supporting the position is provided at the bottom of the heparin cap body 11, the second high platform 5 is provided with a compression arc hole 51, and the second high platform 5 has a deformation section 54 for reflecting the position of the heparin cap body 11.

[0029] In this embodiment: the outside of the puncture needle body 1 is provided with a first transparent dressing body 2 for attaching the puncture position, and the first transparent dressing body 2 is provided with a central setting hole 21. When the puncture point is fixed, after the first transparent dressing body 2 is attached and fixed, the position of the puncture needle body 1 can be conveniently found under the action of the central setting hole 21, and the position of the catheter and the heparin cap body 11 can be distributed according to the position of the central setting hole 21. The first transparent dressing body 2 is fixedly connected with the second transparent dressing body 3, and the second transparent dressing body 3 covers the outside of the central setting hole 21. The first transparent dressing body 2 and the central setting hole 21 cover the tail end of the needle body. The skin at the puncture point is routinely disinfected, and after it is completely dry, a sterile transparent film dressing is taken for use. After the first transparent dressing body 2 is used, and the puncture needle body 1 is in the puncture state, the second transparent dressing body 3 can be used. The heparin cap is higher than the tip of the catheter and parallel to the blood vessel, and the puncture date and time, the puncturist's work number, are recorded, and the isolation plug of the indwelling needle is sealed with tape.

[0030] One of the three adhesive bodies 41 is fixed on the exposed catheter, another seals the outlet of the catheter, and the other is fixed in the middle of the two, so that the three adhesive bodies 41 are fixed on the exposed catheter, seal the outlet of the catheter, and are fixed in the middle of the two. After that, the first pedestal 42 covers the outside of the catheter. The three adhesive bodies 41 are all located outside the first pedestal 42. There are two attached pressing arc plates 43 on the outside of the first pedestal 42. The two attached pressing arc plates 43 are symmetrically distributed. The outside of the attached pressing arc plate 43 has an attached surface 431. A connecting rod 44 is fixedly connected to the outside of the attached pressing arc plate 43. The connecting rod 44 has elasticity. The connecting rod 44 is slidably connected to the first pedestal 42. A pressure sensor 45 corresponding to the connecting rod 44 is arranged in the first pedestal 42. Under the action of the first pedestal 42, the fixed position can be restricted, so that the adhesive body 41 compresses the attached pressing arc plate 43. The fixed state is analyzed according to the position of the connecting rod 44 close to the pressure sensor 45. If the adhesive body 41 loosens, the attached pressing arc plate 43 will slowly reset under the elasticity of the connecting rod 44. The pressure sensor 45 can be directly a spring type. At this time, the pressure sensed by the pressure sensor 45 becomes smaller. By setting an alarm, information can be fed back in time.

[0031] The heparin cap body 11 is fixed according to the position of the central setting hole 21. After restricting the positions of the heparin cap body 11 and the second pedestal 5 through adhesive tape, the heparin cap needs to be higher than the catheter tip to avoid pressing on the local skin. Two position-fixed reaction rods 53 are fixedly connected in the compression arc hole 51. A distance sensor 52 is fixedly connected in the deformation section 54. The distance sensor 52 is opposite to the position-fixed reaction rod 53. Both the first pedestal 42 and the second pedestal 5 are soft pads. The fixed state is analyzed according to the distance between the distance sensor 52 and the position-fixed reaction rod 53. When fixing the heparin cap body 11, the second pedestal 5 can be compressed, so that the deformation section 54 changes towards the position of the compression arc hole 51. At this time, there is a fixed distance between the position-fixed reaction rod 53 and the distance sensor 52. If the distance changes, it may indicate that the outer adhesive tape is loose. By setting an alarm, information can be fed back in time to inform the medical staff in time. If there is a position change, it can be repaired in time to improve the stability during puncture treatment.

[0032] As Figures 1 to 5 shown, the present invention also provides a usage method of a cerebrovascular puncture fixing device for neurointervention. The specific steps are as follows:

[0033] A: When fixing the puncture point, after attaching and fixing the first transparent dressing body 2, it is convenient to find the position of the puncture needle body 1 under the action of the central setting hole 21. At the same time, the positions of the catheter and the heparin cap body 11 can be distributed according to the position of the central setting hole 21;

[0034] B: Three adhesive bodies 41 are fixed on the exposed catheter, sealing the outlet of the catheter. After being fixed at two intermediate positions, under the action of the first pedestal 42, the fixed position can be restricted, enabling the adhesive body 41 to compress and adhere to the pressing arc plate 43, and analyzing the fixed state according to the position of the connecting rod 44 close to the pressure sensor 45;

[0035] C: The heparin cap body 11 is fixed according to the position of the central setting hole 21. After restricting the positions of the heparin cap body 11 and the second pedestal 5 with adhesive tape, the fixed state is analyzed according to the distance between the distance sensor 52 and the position-fixed reaction rod 53.

[0036] The working principle of the present invention is as follows: When fixing the puncture point, after the first transparent dressing body 2 is attached and fixed, the position of the puncture needle body 1 can be conveniently found under the action of the central hole 21. At the same time, the positions of the catheter and the heparin cap body 11 can be distributed according to the position of the central hole 21. A second transparent dressing body 3 is fixedly connected to the first transparent dressing body 2. The second transparent dressing body 3 covers the outside of the central hole 21. The first transparent dressing body 2 and the central hole 21 cover the tail end of the needle body. The skin at the puncture point is routinely disinfected and waited until it is completely dry. Then, a sterile transparent film dressing is used. After the first transparent dressing body 2 is used and the puncture needle body 1 is in the puncture state, the second transparent dressing body 3 can be used.The heparin cap is higher than the catheter tip and parallel to the blood vessel. Record the puncture date and time and the operator number of the puncturer. Seal the isolation plug of the indwelling needle with tape. One of the three adhesive bodies 41 is fixed on the exposed catheter, another seals the outlet of the catheter, and the other is fixed in the middle of the two, so that the three adhesive bodies 41 are fixed on the exposed catheter, seal the outlet of the catheter and are fixed in the middle of the two. Then, the first pedestal 42 covers the outside of the catheter. The three adhesive bodies 41 are all located outside the first pedestal 42. There are two attached pressing arc plates 43 on the outside of the first pedestal 42. The two attached pressing arc plates 43 are symmetrically distributed. The outside of the attached pressing arc plate 43 has an attachment surface 431. A connecting rod 44 is fixedly connected to the outside of the attached pressing arc plate 43. The connecting rod 44 has elasticity and is slidably connected to the first pedestal 42. A pressure sensor 45 corresponding to the connecting rod 44 is arranged in the first pedestal 42. Under the action of the first pedestal 42, the fixed position can be restricted, so that the adhesive body 41 compresses the attached pressing arc plate 43. Analyze the fixed state according to the position of the connecting rod 44 close to the pressure sensor 45. If the adhesive body 41 becomes loose, the attached pressing arc plate 43 will slowly reset under the elasticity of the connecting rod 44. The pressure sensor 45 can be directly a spring type. At this time, the pressure sensed by the pressure sensor 45 becomes smaller. By setting an alarm, information can be fed back in time. The heparin cap body 11 is fixed according to the position of the central setting hole 21. After restricting the positions of the heparin cap body 11 and the second pedestal 5 with tape, the heparin cap needs to be higher than the catheter tip to avoid pressing on the local skin. Two position-fixed reaction rods 53 are fixedly connected in the compression arc hole 51. A distance sensor 52 is fixedly connected in the deformation section 54. The distance sensor 52 faces the position-fixed reaction rod 53. Both the first pedestal 42 and the second pedestal 5 are soft pads. Analyze the fixed state according to the distance between the distance sensor 52 and the position-fixed reaction rod 53. When fixing the heparin cap body 11, the second pedestal 5 can be compressed, so that the deformation section 54 changes towards the position of the compression arc hole 51. At this time, there is a fixed distance between the position-fixed reaction rod 53 and the distance sensor 52. If the distance changes, it may indicate that the outer tape is loose. By setting an alarm, information can be fed back in time to inform the medical staff in time. If there is a position change, it can be repaired and fixed in time to improve the stability during puncture treatment.

[0037] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
